RE: Schrodinger's Cat. What say you?

I agree with your late friend. The thought experiment is invalid because the cat is the observer.
Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.

There's a cat in the box?

The point of view of the cat is immaterial - it is the subject of the experiment, not the observer. In the original formulation, the subject was a keg of gunpowder that could exist in the superposition of exploded/unexploded. No one would seriously contend that a keg of gunpowder is the observer of the experiment.
The experiment isn’t about a cat.

He was wrong. "You don't know, until you look "is one thing. But, " I do know because I don't know, because I left out other parameters" is exactly what he did.
QM and PM are not defending "anything goes" as the cat thought experiment would suggest.
Of course they’re not defending it. The thought experiment was constructed to show that Shrodinger and Einstein thought that superposition was absurd. It appears that they were wrong.

Tell that to the cat.
There's no cat. There never was a cat. It was a
thought experiment about quantum events (in this case, radioactive decay) influencing macroevents. And it seems fairly sure that observation and measurement
do collapse the wave front.

"Spooky at a distance" could mean that ABBA are the ultimate Gods of the universe. Pretty sure everyone reading this is laughing right now.
